A:
The borrower should pay the loan in the same currency with which he borrowed the capital. And if he wants to pay in a different currency, this has to be done according to the value of the Dollar at time of settling the loan. However, a Muslim may not stipulate that upon concluding the loan contract, because this will be paying without mutual exchange and this is not permissible for what is mentioned in the Hadith narrated by `Ubadah. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
